It plays okay on my machine as long as I dumb-down the graphics.
It was running sweet on my kids' PC until something kept making the computer freeze on the "Welcome" screen during boot-up. I had to do a system roll-back to before I installed the demo, and the computer is fine now. I haven't had the time to re-install it to see if it locks it up again.
